\chapter{Conclusion}

We have prototyped a new innovative approach to VoIP management called L3DGEWorld Asterisk Management Systems (LAMS). LAMS is designed to be implemented onto an existing IP network that has currently or will be running a VoIP system. Our system prototype is based on a data visualisation utility called L3DGEWorld and a VoIP telephony engine called Asterisk. 

The LAMS prototype allows up to eight users (more specifically network administrators) to view the entire VoIP system in a virtual world. We have created a virtual world where 3D entity display VoIP information such as the number of current calls. These entities have visual characteristics that inform a network administrator about the state of the VoIP system. Our prototype is limited to viewing the number of calls that are represented by entities in the LAMS virtual world. The architecture is in place to allow users to interact with 3D entity objects and perform administrative tasks, but this feature was not included in the prototype, due to time constraints and its nescessity as a proof the LAMS concept.

We throughly tested the LAMS prototype for network overhead, hardware requirements and success in conveying monitoring information. From our performance analysis we can state that LAMS can be deployed onto an existing VoIP service with the following statements and conditions:
%\begin{itemize}
%\item Each LAMS server can monitor a cluster of 11 VoIP servers where each serves 90 VoIP clients.
%\item The traffic generated by monitoring up to 20 VoIP servers has a negligible network rate of 10 Kbytes per second.
%\item LAMS clients (network administrators) should only connect from within the same network as the LAMS server to achieve close to real time monitoring as delays can affect the perceived state of the VoIP system.
%\end{itemize}

The LAMS prototype constrasts the difference between displaying information in a 2D and 3D. The 2D fashion using graphs and tables has its advantages of showing the history of the item being monitored. On the other hand using 3D visualisation of information proves to be useful when viewing the current status of the system and watching out for any system alerts.

This project has the potential to revolutionise the VoIP management market. We believe other commercial VoIP management products can utilise the concepts of our project. Combining the standard 2D and 3D approaches, management of VoIP will become an easier task to accomplish.
